    Resolution Note (fix version 2021.1):

    Fixed a bug where calling unityInstance.Quit() from JavaScript (and releasing all references to unityInstance) would not let JS VM garbage collect away the Unity game application. Fixed in Unity 2021.1.0a2 and above

    I see this bug also in 2020.3 LTS, which seems an important bug from where we stand. It's really important for our project.
